FMR1 and fragile X syndrome: SCZ in the FXS condition is poorly documented in clinics, and only a case study has so far reported SCZ symptoms in an individual with FXS [125], therefore future clinical studies are necessary to further explore this possible link. Overall, our findings indicate that critical periods of brain development are especially vulnerable to immune insults, which can lead to significant long-lasting changes, such as the alteration of FMRP levels, ultimately affecting synaptic plasticity and behavioral outcomes.
